[PATCH] alsa-utils: Install and delete from the same udev-rules-dir

[Ola x Nilsson <ola.x.nilsson@axis.com>]

The --with-udev-rules-dir option used with udev is exactly what the
configure script uses, so there is no need for it.
On the other hand, if we do not have an udev.pc file we should tell
alsa-utils where to install the rules so we know where they should be
deleted from.
